I've run into an odd occurrence where I my game will start as normal, and I can open all of my menus and move around and such, until I switch back to ORK Framework while the game is running. Switching from the game screen to framework screen also seems to work, although there's a bit of lag, but then, when I switch back from framework to the game screen I get this old chestnut:
NullReferenceException: Object reference not set to an instance of an object
Ad infinitum=infinite loop. So, it seems that the simple act of accessing my framework is breaking something crucial, possibly in multiple instances. Several times I was able to avoid this by deleting all of my menu screens before switching back from framework to game, but this doesn't consistently work. Any ideas?
